What color represents moderate precipitation on the NEXRAD display?

The correct choice for moderate precipitation on the NEXRAD display is indeed purple. In the NEXRAD (Next-Generation Weather Radar) system, various colors are used to indicate different levels of precipitation intensity. Specifically, purple typically signifies areas of moderate precipitation. This color coding system helps air traffic controllers, pilots, and meteorologists quickly assess weather conditions and make informed decisions.

In the context of the other colors, green generally indicates light precipitation, yellow shows areas of heavy precipitation, and red is used to represent very heavy precipitation or severe weather conditions such as thunderstorms. Understanding this color coding is crucial for effective monitoring of weather patterns that can impact aviation safety and route planning.
